RESPIRATOR Filed Feb. 11, 1953 2 Sheets-Sheet 2 Patented Dec. 8, 1936 UNITED STATES PATENT OFFICE 7 Claims.

My present invention relates to new and useful improvements in a respirator and in so far as there is common subject matter the present application is a continuation in part of my applications filed September 22, 1927, Serial No. 221,316 (Patent No. 1,802,275, dated April 21, 1931) and July 8, 1929, Serial No. 376,700.

The principal object of the invention resides in the provision of a member which may be readily positioned on the nose or removed therefrom and a separate member adapted to be positioned over the mouth and connected to the member which is positioned on the nose.

Another object of the invention resides in the provision of a. member which may be readily positioned on the nose or removed therefrom, wings being provided for swinging movement so that they may be properly positioned over the openings of the nose or left spaced therefrom and. such wings carrying gauze or other suitable material through which the air drawn into the nostril may be filtered.

A further object of the invention consists in the provision of a member adapted to be positioned over the mouth including a frame adapted to carry gauze or other suitable filtering material and means whereby the member may be held in proper position over the mouth, said means including a loop adapted to be engaged with a member positioned on the nose.

Still another object of the invention consists in the provision of a member adapted to be connected to the nose, said member including a frame adapted to be connected to the nose partition and having a depending central portion, members adapted to be engaged with the Walls of the nose, and wings adapted to be adjusted relative to the nose openings. With the above and other objects in view, which will appear as the description proceeds, my invention consists in the novel details of construction, and arrangement of parts, described in the following specification and illustrated in the accompanying drawings, and while I have illustrated and described the preferred embodiments of the invention, as they now appear to me, it will be understood that such changes may be made as will fall within the scope of the appended claims.

In the drawings a indicates the member adapted to be positioned on the nose and 12 indicates the member adapted to be positioned over the mouth. Referring to the member a I indicates a substantially U-shaped frame preferably formed from a strip of resilient metal which may be bent into the desired shape or more particularly into the shape illustrated in Fig. 1 of the drawings with a depending central portion 2 providing a finger grip to be engaged for positioning the member relative to the nose and permitting adjustment or widening of the frame when desired to adapt the same for partitions of different thicknesses. The ends of the strip forming the frame are made to provide the substantially vertically extending eye portions 3 which depend from the frame, and intermediate the ends of the frame the strip is made to form the inwardly extending arms 4 having the substantially horizontally extending eyes 5 formed at the inner ends thereof. As quite clearly shown in Fig. 1 of the drawings the inner ends of the arms 4, at the points of the eyes 5, are spaced a distance apart so as to receive the partition wall 6 of the nose therebetween. The frame is preferably resilient so that it may be sprung sufficiently to allow the partition wall of the nose to pass between the inner ends of the arms and when released the arms will engage on opposite sides of the partition wall as shown. As previously stated the depending portion 2 permits the frame to be adjusted or widened at will.

Extending through the eyes 5 of the arms 4, and frictionally held therein, are the rods I having their inner ends bent to form the arms 8 and the extensions 9. The arms, as quite clearly shown in Fig. 1 of the drawings, extend outwardly in opposite directions to engage the inner surfaces of the outer walls of the nose. The extensions 9 are adapted to engage the lip In just below the nose as shown more particularly in Fig. 2 to aid in holding the device in position on the nose.

Mounted on the rods I, and frictionally held thereon, are the sleeves or tubes II which are positioned between the extensions 9 and the ends of the eyes 5, these sleeves or tubes being adjustable on the rods to position the rods or extensions 8 to properly position and hold the frame I on the nose partition, it being understood that the ends of the tubes or sleeves will engage the ends of the eyes 5.

Extending through the depending substantially vertically extending eyes 3 are the rods I2, said rods being of such a diameter as to snugly fit the interior of the eyes and adapted to be held by friction. The lowerends of the rods are bent in the manner shown to form the portions I3 and I4 with the diagonally extending arms I5 formed on the ends of the portions I4. The arms I5 will receive the wings to be later described and particular attention is directed to the fact that the rods I2 are rotatably mounted in the eyes but are held against sliding movement by means of the inturned extensions I6 formed on the lower ends of the eyes 3, as shown more particularly in Fig. 2 of the drawings. The extensions I6, as shown, engage beneath the portions I3. The rods I2 being rotatable in the eyes permit adjustment of the rods I5 to properly position the wings carried thereby, beneath the openings of the nose.

The wings which are both slidably and rotatably mounted on the arms I 5 consist of frame portions which are covered by gauze or other similar material. The construction of the frame portions of the wings is quite clearly illustrated in Fig. 3 of the drawings and each of the frames consists of the three sections indicated at H, I8 and I9, the sections being connected together for sliding ad justment whereby the'size of the frame may be adjusted as desired. The section I1 is formed at the outer end with an eye 20 through which the arm I5 is adapted to extend. This eye is of such a diameter as to snugly fit the arm I5 so that there will be sufficient friction to hold the wing in its adjusted positions relative to the arm. The section I8 is provided at each end with the inturned flanges. 2I forming guides for the ends of the sections I1 and I9, as shown more particularly in Fig. 3 of the drawings and the section I9 in cludes an arm 22 which extends parallel with the section I'I. Each of the sections I8 is provided on one face with an outwardly extending pin 23 and each of the sections I9 at the juncture with its arm 22 is provided with a similar pin 24, these pins being used for purposes to be later described. A pocket of gauze or similar material is adapted to receive each of the frames and to form a part of the adjustable wings as shown in the drawings, one of the pockets of gauze being shown at 25 and the other at 26. the pocket 25 having the extension 21 for a purpose to be later described. The pins 23and 24 will engage and extend through the gauze pockets and thereby hold the same upon the frames and when the frames are swung as shown in Figs. 1 and 4 into the position over the nose openings the extension 21 will be engaged with the pins 23 and 24 on the opposite frame and extend over the space between the adjacent edges of the two frames. Each of the wings is provided,

at the end of the arm 22, with a hook or projection 28 for a purpose to be later described and when the wings are swung to cover the nose openings the hooks or projections will be in close proximity as they are on adjacent portions of the wings.

From the above detailed description of the member to be attached to the nose it is thought that the construction and manner of using will be readily understood. The member is adapted to. be attached to the nose and the wings carrying the gauze or other filtering material are adapted to be swung into position over the nose openings as shown more particularly in Fig. 1 of the drawings. When applying the-member the depending portion 2 will be grasped for positioning the frame I upon the nose partition 6, as shown more particularly in Fig. l of the drawings and the arms 8 will be positioned so that their ends engage the inner faces of the walls of the nose while the extensions 9 will engage the lip I of the wearer just below the nose as shown more particularly in Fig. 2. As previously stated if it is desired to widen the frame I this can be done by springing the ends of the arms 4 apart, the depending portion 2 permitting this adjustment. With the frame thus attached to the nose the wings will be adjusted so that the filtering material forming a part thereof will extend beneath and cover the nose openings. The rods I2 are rotatably mounted in the sleeves 3, as previously stated, and the wings or frames are adjustable on the arms I5 for either rotatable or slidable movement. The arms I5 will extend through the gauze covering the frames or wings when entering the sleeves or eyes 20. The rods I2 are held against any sliding movement within the sleeves or eyes 3 by means of the inturned extension I6 as shown more particularly in Fig. 2 of the drawings. In removing the device from the nose the extensions 9 will be grasped and manipulated to rotate the rods I in the eyes 5 so as to swing the ends of the arms 8 from engagement with the walls of the nose and in position to be withdrawn from the nose openings. In applying the device the extensions 9 will be engaged and moved in the opposite direction to engage the ends of the arms with the Walls of the nose.

The member adapted to be positioned over the mouth is shown more particularly in Figs. 6, '7, 8, 9 and 10 of the drawings and includes the frame 29 and gauze covering 30, this covering 30 acting as the filtering material. Secured to opposite ends of the frame are the resilient or adjusted therein. Each of these loops or sleeves 3I has a hook portion 3I' engaged through the fabric and with the ends of the frame. Secured to the outer end of each of the bands 32 is a connecting member or guide including the resilient sleeve 33 and eye 33', the eye being positioned at right angles. to the sleeve 33. The elastic bands 32 are held in the sleeves 33 by friction and extending through the eyes 33' are the opposite ends of an elastic band 34, the ends of the bands being held within the eyes by'friction but adapted for adjustment therethrough. The ends of the band 34 are connected by means of a resilient sleeve or clip 35 shown more particularly in Fig. 6 of the drawings, and as shown also in this figure when the mouth attachment is in position the band 34 will extend around the head of the wearer whereas the connected ends of the band form a loop portion indicated at 36 which is adapted to extend beneath the chin. It will thus be seen that the bands 32 as Well as the band 34 are adapted for adjustment to permit the attachment to be worn by persons with different size heads. Secured to the upper edge of the fabric 30, intermediate the ends thereof, is a loop 31 which is adapted to be engaged with the hooks or extensions 28, on the nose member whereby the mouth attachment may be connected to the nose member and held in proper position relative thereto. Carried by the band 34 are the sleeves or stops 38, which are adapted to engage the eyes 33', as shown more particularly in Fig. 7 of the drawings, to properly position, after adjustment, the ends of the band 3 t relative to the bands 32.

A respirator such as I have described and illustrated is of particular advantage in preventing the entrance of impurities into the nose or mouth and may be worn by travelers in trains or motor vehicles, by engineers or firemen, by those who suffer from hay fever or the like to prevent pollen from entering the nose or mouth, or in fact, by anyone who desires to prevent the entrance of dust or other impurities into the nose or mouth. By having the several parts adjustable, as has been described, the device is adapted for use under varying conditions and the filtering material may be changed when desired.
